The new elaborated asymptotic method is allowed to redused the solution of complicated problems of nonlinear materials to subsequently solved boundary problems of potential theory. Analytical solutions and numerical results of new contact problems with different contact conditions are obtained.The elaborated approaches have a wide application in problems on strengthening shells, wave processes and nonlinear problems for finite dimensional bodies. The results can be used for constructions of flier apparats, anysotropic and composite materials and in the educational institutions. Product Description popup.authors popup.nrat_date 2020-04-02 Close
